I just got finished watching these. Corny and overacted by our standards but Well Worth a look. No "bad guys" just stories of people. The battle scenes appear to have been shot all at once for all three films by the same producer.
"Three Civil War films by legendary producer Thomas Ince, made nearly 50 years after the conflict's end, offer a unique look at the ravages of bloodshed. "The Drummer of the Eighth" (1913) focuses on a young boy who follows his brother into the Union Army. "The Coward" (1915) follows a young man as he confronts his fear of battle. "Granddad" (1913) chronicles the relationship between a Civil War veteran and his granddaughter."
Granddad actually made me cry! Final scenes appear to have been shot at a real Memorial Day ceremony.
